Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.

WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Blue shark is represented by about 3.8 m / 12.5 ft; Lemon shark by commonly to 3 m / 10 ft. Upper records are uncommon; most adults are lighter. The values are upper-end figures, not a typical adult profile.

Bite evidence

Blue shark: No comparable maximum is used. Lemon shark: No standardized maximum is available for a fair cross-species comparison.

Living versus extinct

Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.

Ecology changes the matchup

Its long fins and slender build matter more than raw bulk. Decades of field research make this one of the best-studied coastal sharks.
